Now the new kit is better, before this no improvement. Heck you took the pics, and they weren't even taken from similar angels. You haven't answered why you have a problem porting one. Aside from a bad bore or plating, or ports cast way out of place, porting should be straight forward. What is bad about the cylinder if it is ported? A novice should be able to make one run pretty good. I still say run it stock or send it to someone that will.
I have a 440 torn down on the bench just waiting for him to send it.
